A ruby analog of lodash#get.

got.rb

module MyModuleName
  # Safely navigate a hashmap via dot-notation, similar to lodash#get.
  # May return nil; Assumes string keys, will not work for symbols!
  #
  # Example Usage:
  # got(foo, 'bar.fizz.buzz')
  def got(object, dot_notation_path, default_value = nil)
    # FIXME: Does not support OpenStruct!    -uly, july 2016
    keys = dot_notation_path.split('.')
    while !keys.empty? && !object.nil?
      object = object.is_a?(Array) ? nil : object.try(:fetch, keys.shift, nil)
    end
    object.nil? ? default_value : object
  end
end
